1 Claim. 1 This invention relates to improvements in socket wrenches.

An object of the invention is to provide a-collapsible socket wrenchthat win tighten nuts on rods or cables that cannot be reached by theconventional type of socket wrench in use at the present time.

Another object of the invention is to provide a wrench that is formed ofa few simple parts that is durable in use, efficient in operation andcan be manufactured inexpensively for the purpose designed.

With the above and other objects and advantages in view, the inventionconsists of the novel details of construction, arrangement andcombination of parts more fully hereinafter described, claimed andillustrated in the accompanying drawing in which:

Figure 1 is a perspective view of an embodiment of the invention;

Figure 2 is an elevational view partly in section each jaw, but sincenuts for varying purposes may have an innumerable number of faces, thejaws may have any number of faces, as desired, to accomplish therequired operative use thereof.

Jaw II has a tongue l5 at one end which is received in the bifurcatedend 16 of the jaw l2, and the jaws are apertured at I! to receive thepintle pin l8 whereby the jaws are pivotally connected for movement onthe pin I 8.

Each jaw, at the end opposite to the pivoted end thereof, is providedwith an upstanding vertical projection l9 having flat engaging faces 20,and when these faces are in engaging contact with each other,ethe socket2| of a handle 22 may be placed thereover to hold the jaws in engagementwith a nut 23 for the loosening thereof.

' In Figure 2, wherein there is shown the man ner in which the wrench isused, the numeral 24 designates a bulkhead having a rod 25 passing 2therethrough, and secured thereto by a nut 26 on one side of thebulkhead and the nut 23 on the other side. The jaws are opened on thepintle l8 and slipped around the nut 23, then with the socket 2!engaging the projection I9, the nut may I be loosened by manipulation ofthe handle 22.

It is believed that from the foregoing description, the operation andconstruction of the invention will be apparent to those skilled in theart, and it is to be understood that changes in the minor details ofconstruction, arrangement and combination of parts may be resorted to,rovided they fall within the spirit of the invention and the scope ofthe appended claim.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

A wrench comprising a pair of complementary jaws connected for pivotalmovement to open or closed position, a pair of upstanding, juxtaposedlugs, each integral with an end portion of one of the jaws,diametrically oppositethe pivotal connection for the jaws and extendingin parallel planes at right angles to the plane of the jaws, and amember for cooperation with both lugs, which member is provided with a,socket portion at one end for reception of both lugs in their juxtaposedposition, and with an elongated handle in axial alignment with thesocket portion, whereby the socket portion, in cooperation with thelugs, holds the jaws in locked engagement with a nut element to beturned, and the handle may be manipulated to operate the wrench.
